C-450 & SL-450 Cylinder Finishers

 

 

 

GOMACO Corporation pioneered the development of the first cylinder finisher over 50 years ago. The late Harold W. Godberson, founder of GOMACO Corporation, developed and manufactured a bridge deck finisher to meet the growing needs for bridge markets. Considered to be a milestone, the cylinder finisher made GOMACO a recognized name in the construction industry.

Today, GOMACO cylinder finishers are designed for versatility with the C-450. It is easy to operate and saves time and labor costs on all of your concrete finishing projects.

Pin-connected sections provide fast setup time and the versatility to fit exact job requirements. The C-450 frame widths range from 12 feet (3.66 m) to 104 feet (31.7 m), with transitional framework attached.

 

 

 

 

Transitional Framework

GOMACO Bridge Deck Finishers - Available with Transitional Framework and Third Wheel Assist

The transitional framework is a design option for the GOMACO C-450 cylinder finisher that provides faster assembly and weight savings compared to wider-width finishers requiring an overhead truss system. The new frame features transition sections connecting the C-450’s standard 24 inch (610 mm) tall framework to the 42 inch (1067 mm) tall framework used on a C-750 finisher. The frame sections only need to be pin-connected and the cross arms bolted in place.

The transitional framework sections can also be removed and the C-450 can finish at smaller widths with its standard 24 inch (610 mm) framework. The framework allows the versatility of two finishers in one for the narrower or wider widths. The transitional framework can be added to new or existing C-450s.

GOMACO’s line of bridge deck finishers is also available with the optional third wheel assist on the standard bogies to further distribute the machine’s weight while traveling on the rails. The optional third wheel assist bogies, on each side of the finisher, consist of two single-wheel idler bogies attached to the spreader beam. It’s a simple modification that can be made to any C-450 or C-750 to help spread the weight out and reduce the wheel load on the overhang brackets.

 

 

The C-450’s transitional framework allows for wider finishing. It has a quick assembly time since the frame sections only need to be pin-connected and the cross arms bolted into place.

Versatile Frame and Finishing Width...

The frame width for the standard C-450 cylinder finisher is 12 feet (3.66 m) to 72 feet (21.95 m). The frame width on the C-450 with transitional framework is a minimum of 12 feet (3.66 m) to a maximum of 104 feet (31.7 m).

 

 

 

 

 

 

 

SL-450 Conversion Kit

The GOMACO C-450 can be converted to an SL-450 with the slope paver conversion kit. The kit includes four slope adapter jack mounts, two stationary jack mounts, carriage engine slope mounts, slope idler sprocket assemblies, drive chain, end panel drive sprockets, carriage wheels, and two hydraulic motors. The complete slope paver conversion kit is specifically designed for field installation. The SL-450 is designed for fast trimming and finishing, strict tolerances, even on 1:1 (45 degree) slopes, with a minimum of handfinishing.
